Danish shipping giant A.P. Moeller-Maersk will offer 2.3 billion euros ($3.0 billion) in cash to buy Dutch rival P&O Nedlloyd, solidifying its position as the world's top container line, Reuters reported. P&O Nedlloyd will back the intended offer of 57 euros per share, which represents a 40.6 percent premium over its May 9 price before the tie-up talks were announced on Tuesday, the companies said in a joint statement on Wednesday.
